  • Publication number: 20160297303
    Abstract: A control device for electric motor vehicle is configured to decelerate by a regenerative braking force of the motor when an accelerator operation amount decreases or becomes zero. The control device detects the accelerator operation amount, calculates a motor torque command value, and controls the motor on the basis of the motor torque command value calculated. The control device detects a speed parameter proportional to a traveling speed and calculates a feedback torque for stopping the vehicle on the basis of the speed parameter detected. The control device also estimates a disturbance torque acting on the motor and converges, as the speed parameter is reduced, the motor torque command value to the disturbance torque on the basis of the feedback torque when the accelerator operation amount decreases or becomes zero and the electric motor vehicle stops shortly. The control device adjusts the feedback torque according to the disturbance torque.

  • Publication number: 20160300998
    Abstract: A method for producing a magnetostrictive material and a method for increasing the value of magnetostriction can increase the value of magnetostriction of magnetostrictive materials used, for example, in vibration power generation and force sensors utilizing inverse magnetostriction phenomenon. A magnetostrictive material having a value of magnetostriction of 100 ppm or more is produced by melting and casting an alloy material in the composition of range of 67-87 wt % Co with the balance consisting of Fe and unavoidable impurities and then performing hot forging. Furthermore, a magnetostrictive material having a value of magnetostriction of 130 ppm or more can be produced by performing cold rolling after the hot forging. Heat treatment at 400-1000° C. may also be performed after hot working or cold working.

  • Publication number: 20160297321
    Abstract: A control device for electric motor vehicle configured to decelerate by a regenerative braking force of the motor detects an accelerator operation amount, calculates a motor torque command value and controls the motor on the basis of the calculated motor torque command value. Further, a speed parameter proportional to a traveling speed is detected, and a feedback torque for stopping the electric motor vehicle is calculated on the basis of the detected speed parameter. Furthermore, the speed parameter is estimated in accordance with a state of the electric motor vehicle, and a feedforward torque is calculated on the basis of the estimated speed parameter. When accelerator operation amount is not larger than a predetermined value and the electric motor vehicle stops shortly, the motor torque command value is converged to zero on the basis of the feedback torque and the feedforward torque with a reduction in the traveling speed.
